Description
Technical Field
[0001] This utility model relates to the field of sanitation vehicle technology, specifically to a sanitation vehicle suction nozzle assembly. Background Technology
[0002] In existing sanitation vehicles, the suction nozzle is the primary component for garbage collection during road sweeping. As one of the most crucial parts of a sanitation vehicle, the suction nozzle directly impacts its dust collection efficiency. During operation, the nozzle height needs to be adjusted according to road conditions and garbage type to better conform to the ground and avoid collisions. When the entire nozzle assembly needs to be raised, the existing airflow baffle height cannot be adjusted in time, resulting in reduced negative pressure at the nozzle's edge. This reduces the suction force, leading to incomplete garbage collection. Alternatively, when garbage is large, the inability to adjust the airflow baffle height in time can cause it to be blocked, leaving residue after sweeping and reducing overall cleaning performance.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 5 As shown, this utility model provides a suction nozzle assembly for sanitation vehicles.
[0024] Example 1:
[0025] This embodiment provides a sanitation vehicle suction nozzle assembly, disposed on the underside of the sanitation vehicle floor. It includes a suction nozzle body 1 and a vertically movable suction body 2 within the suction nozzle body 1. The suction body 2 is driven by a movable component 3. One end of the movable component 3 passes through the suction nozzle body 1 and is fixedly connected to the suction body 2; the other end of the movable component 3 is disposed on the upper side of the suction nozzle body 1 and fixedly connected to the sanitation vehicle floor 7. The suction nozzle body 1 can move vertically relative to the sanitation vehicle floor 7. The drive structure that drives the suction nozzle body 1 is prior art and will not be specifically described in this embodiment. The bottoms of both the suction nozzle body 1 and the suction body 2 are open. When the road surface is uneven, the drive structure moves the suction nozzle body 1 upwards. The movable component 3 drives the suction body 2 to remain stationary, move downwards, or move upwards, ensuring the negative air pressure at the intake of the suction body 2, allowing it to completely suck up the garbage. When the garbage is large, the suction body 2 blocks it on its outside. First, the movable component 3 drives the suction body 2 upwards, moving the garbage to the bottom of the suction body 2, or the suction body 2 moves to the top of the garbage. Then, the movable component 3 drives the suction body 2 downwards. This ensures that larger garbage enters the bottom of the suction body while maintaining the negative air pressure at the intake of the suction body 2, allowing it to be completely sucked up. This results in no residual garbage after cleaning, effectively improving the performance of the sanitation vehicle's suction nozzle assembly in cleaning garbage.
[0026] The suction nozzle body 1 in this embodiment includes a suction nozzle outer cylinder 11, which is connected to a suction nozzle top plate 12. Suction nozzle side plates 13 are provided on both sides of the suction nozzle top plate 12. One side of each of the two suction nozzle side plates 13 is connected to a suction nozzle rear plate 14, and the suction nozzle rear plate 14 is sealed to the suction nozzle top plate 12. The suction nozzle top plate 12, the suction nozzle side plates 13, and the suction nozzle rear plate 14 form a suction cavity 15. The top of the suction cavity 15 is connected to the suction nozzle outer cylinder 11. The suction end of the suction body 2 is slidably embedded in the suction cavity 15, and the suction end of the suction body 2 is slidably embedded in the suction nozzle outer cylinder 11. The moving part 3 is slidably and sealed to the suction nozzle top plate 12.
[0027] Example 2:
[0028] Based on Embodiment 1, Embodiment 2 provides a specific structure for the suction body 2. The suction body 2 includes a suction cylinder 21, a front airflow baffle 22, a rear airflow baffle 23, a suction top plate 24, and a suction side plate 25. The front airflow baffle 22, the rear airflow baffle 23, the suction top plate 24, and the suction side plate 25 form a suction cavity 26. The front airflow baffle 22 forms a front air intake channel between itself and the ground for air to enter the suction cavity 26 from the front end, and the rear airflow baffle 23 forms a rear air intake channel between itself and the ground for air to enter the suction cavity 26 from the rear end. The suction cavity 26 is connected to the suction cylinder 21 to achieve top exhaust. Air; the suction top plate 24 is fixedly connected to the moving part 3, the suction side plate 25 slides tightly against the suction nozzle side plate 13, the rear airflow baffle 23 slides and is embedded with the two suction nozzle side plates 13 and slides tightly against the suction nozzle rear plate 14, the front airflow baffle 22 slides and is embedded with the two suction nozzle side plates 13. Both the front airflow baffle 22 and the rear airflow baffle 23 are made of elastic plates. The front airflow baffle 22, the rear airflow baffle 23, the suction top plate 24 and the suction side plate 25 are sealed and fixedly connected to ensure the sealing of the suction chamber 26, thereby ensuring the sealing of the suction chamber of the entire suction nozzle assembly and the structural stability, which can be used in various sanitation vehicles with suction nozzles.
[0029] In this example, a set of symmetrical sliding grooves 6 are respectively provided at the front and rear ends of the opposite surfaces of the two suction nozzle side plates 13. One set of symmetrical sliding grooves 6 is slidably engaged with the two sides of the front airflow baffle 22, and the other set of symmetrical sliding grooves 6 is slidably engaged with the rear airflow baffle 23.
[0030] In this example, the height of the front airflow baffle 22 from the plane is greater than the height of the rear airflow baffle 23 from the plane, and the height of the rear airflow baffle 23 from the plane is less than the height of the nozzle rear plate 14 from the plane. This can guide the airflow to be distributed more evenly, reduce airflow turbulence and energy loss, improve suction efficiency, and also help enhance the stability and durability of the suction body 2, thereby improving the performance and efficiency of the nozzle assembly.
[0031] In this example, the front airflow baffle 22 is inclined and the rear airflow baffle 23 is vertical. At the same time, the sliding groove 6 that is slidably engaged with the front airflow baffle 22 is inclined and the sliding groove 6 that is slidably engaged with the rear airflow baffle 23 is vertical. The bottom end of the front airflow baffle 22 is inclined toward the rear airflow baffle 23, so that the suction chamber 26 has an inverted cone structure that is smaller at the bottom and larger at the top. In this way, the suction chamber 26 forms a gradually changing suction channel, which allows the intake airflow to enter in a spiral shape, thereby improving the suction effect.
[0032] In this example, the bottom ends of the front airflow baffle 22 and the rear airflow baffle 23 are both designed in a sawtooth, wave, or zigzag shape. When the airflow passes over the edge of the wave or sawtooth baffle, it generates multiple sets of airflows entering the nozzle cavity from different directions. The airflows collide with each other, easily forming turbulence or multiple small cyclones in the nozzle cavity, producing a tearing effect. This easily picks up the garbage that enters the suction chamber 26 and collects it through the suction tube 21, thereby improving the garbage cleaning effect. In this embodiment, the bottom ends of the front airflow baffle 22 and the rear airflow baffle 23 are sawtooth-shaped.
[0033] In this example, the serrated structure of the front airflow baffle 22 and the serrated structure of the rear airflow baffle 23 are arranged alternately, which helps to promote the mixing and blending of airflows. At the same time, the airflow passes through the baffles more smoothly, further improving the uniformity and stability of the airflow.
[0034] Example 3
[0035] Based on Embodiments 1 and 2, to further prevent suction from occurring in the space between the suction body 2 and the suction cavity 15, Embodiment 3 provides another structure for the front airflow baffle 22. The front airflow baffle 22 is an elastic plate, and the top of the front airflow baffle 22 extends to form a sliding baffle 27. The sliding baffle 27 is also an elastic plate. The symmetrical sliding grooves 6 that are slidably engaged with the front airflow baffle 22 are connected through an elongated hole 4. The elongated hole 4 is vertically arranged and penetrates the top plate 12 of the suction nozzle. A limiting box 5 is provided on the upper side of 12. The limiting box 5 is fixedly connected to the top plate 12 of the suction nozzle. The inner cavity of the limiting box 5 is vertically arranged and extends through the limiting box 5. The limiting box 5 is arranged around the elongated hole 4, and the inner cavity of the limiting box 5 is adapted to the elongated hole 4. One end of the sliding baffle 27 is integrally formed with the front airflow baffle 22. The other end of the sliding baffle 27 slides through the elongated hole 4 and slides into the inner cavity of the limiting box 5. In this way, a sealed space is formed between the sliding baffle 27, the top plate 12 of the suction nozzle, the side plate 13 of the suction nozzle, the rear plate 14 of the suction nozzle, and the suction top plate 24.
[0036] In this embodiment, the front airflow baffle 22 is inclined, the sliding groove 6 that is slidably engaged with the front airflow baffle 22 is inclined, and the elongated hole 4 that is slidably engaged with the sliding baffle 27 is vertically arranged. The part where the elongated hole 4 is connected with the sliding groove 6 has an arc-shaped structure, which facilitates the sliding of the sliding baffle 27.
[0037] Example 4:
[0038] Based on embodiments one to three, this embodiment four provides a specific structure for the moving part 3, including a connecting column 31, a connecting plate 32, and a driving part 33. The driving part 33 is a cylinder or a hydraulic cylinder, which is existing technology. The output end of the driving part 33 is fixedly connected to the connecting plate 32, and the fixed end of the driving part 33 is fixedly connected to the sanitation vehicle floor 7. The connecting plate 32 is fixedly connected to the connecting column 31. The connecting column 31 is also fixedly connected to the suction top plate 24 of the suction body 2 through a sliding through guide hole. When the output end of the driving part 33 moves, the connecting column 31 drives the suction body 2 to move, thereby realizing the instantaneous adjustment of the height of the suction body 2.
[0039] In this example, a guide plate 34 is also provided on the connecting plate 32. The guide plate 34 slides into the inner cavity of the limiting box 5 and is fixedly connected to the sliding plate 27. This is beneficial for pushing the sliding plate 27 to move and is more conducive to the stability of the suction body 2.
[0040] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
